Your concept of fails to take into account the relativity of size. Humans compared to the macro and microscopic world are humongous.<quoted text>
In the vastness of the universe the entire milky way galaxy hardly registers among the billions of galaxies so one lump of rock circling one of the billions of stars in that mote of a galaxy is nothing. On the universal scale humans are smaller than atoms compared to earth.
Let me put it into proportion for you.
On this lump of rock we call earth humans are the (allegedly) most intelligent of around 8,7 million animal species - nothing
There are myriad more suns in the billions of galaxies in this universe than there are grains of sand on every beach on earth - nothing
Take all the space out of all the atoms of all the 7 billion people on earth and you wind up with an ultra dense object about the size of a sugar cube - nothing
So you are correct, albeit for the wrong reason, humans are nothing - Get that?
Calling people nothing is also a strictly relative concept...you can state "people in size, are nothing compared to to the size of the Universe."
Or people in size are humongous, compared to the size the microscopic Universe.
Size is a matter of perspective...it is not absolute, as you imply.
